In mathematics, the Seifert-van Kampen theorem of Algebraic topology, sometimes it is called as van Kampen’s theorem. It expresses the structure of the fundamental group of a topological space X in terms of the fundamental groups of two open, path connected subspaces u and v that covers X is Abelian group

THE SEIFERT-VAN KAMPEN THEOREM

Seifert & van Kampen introduced the problem of describing the fundamental group of a space X in terms of the fundamental groups of the constituents xi of an open coveringIn mathematics, the Seifert-van Kampen theorem of Algebraic topology, sometimes it is called as van Kampen’s theorem. It expresses the structure of the fundamental group

FREE GROUPS AND FREE PRODUCTS OF GROUPS

One can use van Kampen’s theorem to calculate fundamental groups for topological spaces that can be decomposed into simpler spaces. Thus we can see that there is a commutative diagram including A∩B into A and B and then another inclusion from A&B into s2 and that there is a corresponding diagram of homomorphism b/w the fundamental groups of each subspace. It is clear from this that the fundamental group of s2 is trivial
